Hi, I have for now circumvented the problem. But I did try looking into the correlation values by logging the correlation after the divide block into a file and inspecting the values in Matlab. Here are some statistics: Contiguous samples considered: 4.096e8; # of samples with correlation >

Hi, you should fix the sample rate to 20Msps. Normal WiFi uses 20MHz channels, the other modes are for 11p or communication between SDRs. On 03/26/2017 02:51 PM, Anshul Thakur wrote: > Hi all, > > I'm trying to use the gr-ieee802_11 module with bladeRFs to receive/send > Wifi packets. However,
